EXPERIMENTAL INVESTIGATION ON MECHANICAL PROPERTIES OF ALCCOFINE FLYASH BASED GPC IN COMPARISION WITH GGBS - FLYASH GPC

Abstract

This current work presentsthe results of an experimental program to investigate the possibility of cement substitution in Geopolymer concrete by fly ash and alccofine.GPC mixes were planned and fly ash and alccofine were substituted for cement in 10%,20%,30%...proportions and the same procedure is followed for GGBS and flyash based GPC. Tests were carried out to test Acid attack test (H2SO4), Nitrate attack test (HNO3), Chloride attack test (HCL), Sulphate attack test(Na2SO4), Sorptivity test & water absorption test.The compressive strength of Geopolymer concrete and change in mass percentages wereindicated by the tests results.Geopolymer concrete, including aluminate containing materials with a caustic activator, is set up by reacting silicate. More frequently, waste materials such as GGBS, fly ash, metal slagare used, but the advanced materials like Alccofine enhances the strength and durability properties of GPC even in ambient conditions of curing.By adding various supplementary cement materials, various research literatures on the durability of geopolymer concrete are foreseen as their need increases due to persistent components. Past literature review studies have shown that the replacement of cement with chemical admixtures and mineral admixtures increases the strength and durability characteristics of concrete.Micro structures,higher mechanical properties and superior environmental sustainability are observed.In GPC, elevated temperatures and surface degradation are controlled as opposed to OPC. unlike traditional concrete, GPC provides greater resistance for specimens to acid, sulphates and chemical attack, water absorption and sorptivity,have a strong effect on the durability properties in ambient curing conditions
